We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).

Trailrunner7 (1100399) writes "Google is continuing to introduce new security technologies in its Chrome browser, and the latest addition on the horizon is support for unprefixed Content Security Policy, a behind-the-scenes improvement designed to prevent malicious script injections. The technology is included in the beta of Chrome 25, which was released earlier this week, and will soon find its way into the stable channel.

One of the many attack vectors that have made life easier for the bad guys in the last few years is cross-site scripting. This attack relies on specific vulnerabilities in Web applications that allow attackers to get their own malicious scripts onto a legitimate Web page. Browsers will then run those scripts as if they were part of the trusted Web page, enabling the attacker to plant malicious code on a victim's machine or steal sensitive data.

Content Security Policy is one mechanism for preventing these kinds of attacks by allowing users to define which content sources they trust. Chrome then will run scripts only from those trusted sources, creating a whitelist of known good content sources and ignoring content from all other sources."Link to Original Source

Zothecula (1870348) writes "The Russian Federal Space Agency (Roscosmos) is planning to launch an unmanned spacecraft to the Moon in 2015, a first step toward the ambitious long-term plan to establish a robotic base on the surface of our largest satellite. The spacecraft, called Luna-Glob ("Moon globe"), will be followed by two more orbiters and two rovers that will study the lunar soil locally and collect samples of rocks and dust, bringing them back to Earth for analysis."Link to Original Source

An anonymous reader writes "Raspberry Pi co-creator Eben Upton talks about how the Raspberry Pi Foundation, a tiny British charity, coped with the unexpected global success of the Raspberry Pi, his future plans for the Pi, about fixing flaws in the board and answers critics who claim the board is not as open source as the foundation claims."Link to Original Source

dsinc (319470) writes "Once considered impossible, in 1993 a team of scientists calculated that teleportation could work in principle using quantum laws. Quantum teleportation harnesses the âentanglementâ(TM) law to transmit particle-sized bites of information across potentially vast distances in an instant.

Entanglement involves a pair of quantum particles such as electrons or protons that are intrinsically bound together, retaining synchronisation between the two that holds whether the particles are next to each other or on opposing sides of a galaxy. Through this connection, quantum bits of information â" qubits â" can be relayed using only traditional forms of classical communication.

Previous teleportation protocols have fallen into one of two camps, those that could only send scrambled information requiring correction by the receiver or, more recently, âoeport-basedâ teleportation that doesnâ(TM)t require a correction, but needs an impractical amount of entanglement â" as each object sent would destroy the entangled state.

Now, physicists from Cambridge, University College London, and the University of Gdansk have developed a protocol to provide an optimal solution in which the entangled state is ârecycledâ(TM), so that the gateway between particles holds for the teleportation of multiple objects."Link to Original Source

YokimaSun (930294) writes "Fans of Emulation and Homebrew have not had much to cheer about over the years, the recent generation of consoles have all pretty much killed off any hacking by constant firmware updates. The days of PSP Homebrew have died a death and consoles like the Caanoo, GP2x and even the mighty Openpandora never really lived up to the massive expectation. There is a glimmer of hope from a team of homebrew developers who have developed a new console called the GCW-Zero, a new Open Source Handheld system which uses the OpenDingux Linux OS, the specs are impressive with a Ingenic JZ4770 1 GHz MIPS processor, Vivante GC860, capable of OpenGL ES 2.0, 3.5 inch LCD with 320x240 pixels; 4:3 aspect ratio, 512 MB DDR2 and 16GB of internal memory which can via external memory card be extended by another 32GB. N64 and PS1 emulation and everything below should be at full speed in time."

Over the board (OTB) is one thing, but online (c)heating becomes incredibly hard to detect in situ, for pretty obvious reasons. The online chess community has taken a couple of approaches to detect this. For PlayChess Online (a server that hosts online games), they try to detect if your computer is running another process that is a known Chess Engine while you are playing your game. Easily subverted by having two computers, or even a Virtual Box setup.

The most successful way to detect cheating is in postmortem review. I worked with the ICC/FICS Slow Time Control league team (one guy usually) who would run move correlation statistics off suspicious games. There were lots of parameters in his analysis to tweak: ignore book (pre-planned) openings, use endgame tables, tolerance threshold, plys deep to look, how many branches to examine, etc. I was part one of the peer reviewers of the system and an occasional game. The basic idea was to run the moves through a few engines and find out how high the move correlation was for both players. In certain points of the game, the move correlation is very high because good candidate moves are obvious. However, over a single 35move game (avg), GM correlation with any of the popular chess engines (even HIARCS, which supposedly plays more like a human) was around 23%. 1800 level players (club level) were even less. Magnus Carlsen wasn't on the scene yet; he apparently learned more from the computer than any human. Perhaps he'd be higher. The typical cheater scored around 98%.

This of course is not to say that there couldn't be a player who "thought like a computer". But this would put in question the main criticism of game specific AI, and general AI, that they do not actually model how the human brain thinks. Finding a human who thought like a computer would actually be incredibly interesting to the whole field of AI. That being said, the burden at that point is on the cheater to prove because he is well beyond a reasonable doubt.

I went from an old 300W system down to a 7W Bubba II from Excito. Runs debian and all that entails. Also has a nice WebUI interface for most services (which I've never used). Comes in a few HD configurations. Other than the HD it is completely silent. It's also nice looking, if that matters.

Probably the only thing I wish it had was a sound-card.

I've been using this for a year and have loved it. Perfect for my needs.

jvarsoke (80870) writes "In the last 20 years application development has seen the adoption of great new tools and practices that allow for better, faster and more complex development by larger teams (SVN, JUnit, Clover, CruiseControl, etc). Best of all the tools work for developer — lots of buy-in. But the database engineering side of the house operates like it was still the 1980s. Introducing an IDE and debugger was a big win, but SVN and UnitTesting flopped due to centralized deployment/development platform, and stateful nature of DBs. What does the modern database development environment look like?"
